Outline of Final Research Achievements

Non-destructive tests are required, in principle, to survey heritage structures of masonry for assessment of their seismic safety. In the present research, heritage structures were investigated for seismic or structural diagnosis by employing non-destructive tests such as microtremore measurements, earthquake monitoring utilizing newly-developed accelerometers, crack-displacement monitoring and GPS monitoring. At the same time, analytical approach was introduced to assess seismic safety. On the basis of those data, dynamic soil-structure interaction effect on improvement of their seismic safety, as well as, horizontal in-plane rigidity were investigated. Furthermore, non-destructive test data of earthquake-damaged heritage structures were successfully obtained for their structural restoration.
